Bismarck Raincheck
Two gentleman meet in the sleeper cab of Peterbilt at a rest stop off of I-194, one man (the giver) places a tight band around the other man's (the receiver's) genitals, massages his crotch the point of release, but the band prevents the receiver from ejaculating until after the giver has also finished, thus resulting in a "Bismarck Raincheck".
I was on a cross country trip to my father's funeral when I stopped to give some lonely trucker a Bismarck Raincheck
